Cumberland Plateau TN Fossiliferous Limestone

[LogicViking]

Any IDs y’all can pick out on this rock? I think I see crinoid, but I’m extremely new to this and could use any and all help! Found in a creek on the Cumberland plateau in TN, SCOTT county. Thank you in advance!

You might try getting some close up pics in good light and take them straight on ( like looking down on it ).

When items are photographed at oblique angles, it tends to distort details.

Is this any better? I can’t seem to find any good light!

There may be a trilobite hypostome upper third dead center. Looks like an upside down U similar to this picture from a forum member but not as long.

With the new pictures, I will have to say my hypostome possibility was wrong. I do feel there are possibilities for other trilobite fragments as well as bryozoa and a large brachiopod.
